The link does not at all answer the main question for beginning to evaluate a temperature reconstruction of 125.000 years, that is: how well are the global annual temperature estimated from ice cores, for the years where we do have instrumental data?
By measuring the ratios of different water isotopes in polar ice cores, we can determine how temperature in Antarctica and Greenland has changed in the past.
There might be some truth to this, but A) the fact you don't bother quantifying varying degrees of reliability, and B) the fact that this is your immediate first reaction, makes me highly suspicious of anything you say.

Ah well.
